Explanation
An object with a surface carrying catalyst. Generally, it is a particle, with a size ranging from a few nanometers to over a dozen nanometers. The carrier itself generally needs to have good conductivity, thermal conductivity, thermal stability, chemical stability, and electrochemical stability. The carrier helps the catalyst to form relatively small particles, slows down the agglomeration of particles through its physical chemistry interaction with the catalyst particles, and enables the catalyst layer to have a more appropriate pore size and porosity. There are usually two methods for depositing catalysts on the support. One is to reduce metal ions in the presence of a carrier, which acts as a crystal nucleus, inducing the preferential formation of catalyst atoms and particles composed of these atoms on the surface of the carrier; The second is to first reduce metal ions into atoms, and control the size of particles composed of these atoms through the microenvironment, then add support to adsorb catalyst particles on its surface. 5 There are catalyst support of various shapes on the chemical industry.
